Diagnosis
One or more data records already existed in the database under the IDof the dataset you want to save. To ensure data consistency, these"old" data records were deleted.

System Response
Since the IDs of the datasets which are to be saved are drawn from aunique, non-recycled number range, this situation is the exceptionrather than the rule. If the system does find such a data record, it isalmost certain that the record resulted on account of an error and doesnot belong to a useable saved dataset. It is therefore extremelyunlikely that useful data will be lost when such records are deleted.

Procedure
If this warning occurs frequently, you should inform your systemadministrator as in this case the write activities in the database needto be checked.
It is also possible that the number range in the number range objectwas changed manually. In this case, all datasets with a number whichhas been assigned a second time are deleted from the database.
